(17) No differences have been observed about aspect, odor, pH and volume of ejaculate.
(18) Determining specific ligand-receptor relationships is an extremely challenging task given the diversity of odorants able to be perceived and the potentially large size of the family of receptors.
(19) This review discusses the state of knowledge in odor memory within the framework of mainstream memory research.
(20) When heart rate is used as the index of conditioning, rat pups younger than 15 days of age do not display an odor-shock association.
Pungency
Definition:
(n.) The quality or state of being pungent or piercing; keenness; sharpness; piquancy; as, the pungency of ammonia.
Example Sentences:
(1) Such plants have been used for many centuries for the pungency and flavoring value, for their medicinal properties, and, in some parts of the world, their use also has religious connotations.
(2) When expressed as thermodynamic activity, nasal pungency thresholds remain remarkably constant within and across the homologous series of acetates and alcohols.
(3) Capsaicin analogues, such as olvanil, have similar properties with minimal initial pungency.
(4) Results imply that nasal pungency for these stimuli rests upon a physical, rather than chemical, interaction with susceptible mucosal structures.
(5) The estimation of total capsaicinoids by any simple, reliable method is shown to be adequate for quality control of pungency of Capsicum fruits.
(6) Tarragon's slightly clove-ish pungency makes it a good substi-tute for basil in many dishes.
(7) The rules of additivity of pungency in mixtures need explication.
(8) Two experiments are reported in which the perceptual interactions between oral pungency, evoked by CO2, and the taste of each of four tastants--sucrose (sweet), quinine sulfate (bitter), sodium chloride (salty), and tartaric acid (sour)--were explored.
(9) In experiment 1 the effect of three concentrations of each tastant on the stimulus-response function for perceived oral pungency, in terms of both rate of change (slope) and relative position along the perceived pungency axis, was determined.
(10) Such plants have been used for many centuries for their pungency and flavoring value, for their medicinal properties, and in some parts of the world, their use also has religious connotations.
(11) We measured detection thresholds for nasal pungency (in anosmics), odor (in normosmics) and eye irritation employing a homologous series of acetates: methyl through octyl acetate, decyl and dodecyl acetate.
(12) In three earlier parts in this series, the varieties, cultivation, and primary processing; the processed products, world production, and trade; and the chemistry of the color, aroma, and pungency stimuli have been reviewed.
(13) A comparison with two other spices, namely chilli and cinnamon, suggests a spectrum in which the frequency of symptoms is proportional to the pungency of the spice.
(14) Physiologists have been intensely studying the action of the highly potent pungency stimuli and social psychologists the curious aspect of growing acceptance and preference for the initially unacceptable pungency sensation.
(15) The carrier gas was humidified in order to limit airway irritation caused by the pungency of the volatile agents.
(16) Furthermore, odor was always hypoadditive in mixtures (i.e., mixtures were perceived as less intense than the sum of their components), whereas pungency was, mainly, additive, and even suggested hyperadditivity.
(17) Pungency as a sensory attribute, its evaluation, structure-activity relationship, and its increasing acceptance and preference by diverse populations of the world are of great interest to many research disciplines.
